Flipping the visibility of a screen element.

how to change the visibility of a screen element if a specified condition is satisfied?

Hi,
check this:
if the screen element is called P_TEST for example, you can hide it with the following code in the PBO module of your screen
LOOP AT SCREEN.
    if screen-name cs 'P_TEST'.
      if <HERE IS YOUR CONDITION.....>.
      screen-active = 0.
      MODIFY SCREEN.
     endif.
    endif.
ENDLOOP.
If this element is in the selection-screen, you could do the following:
PARAMETERS: p_test(1).
AT SELECTON-SCREEN OUTPUT.
LOOP AT SCREEN.
    if screen-name cs 'P_TEST'.
      screen-active = 0.
      MODIFY SCREEN.
    endif.
ENDLOOP.
If you just need to show the element but not allow for input, then you can change screen-active = 0. with screen-input = 0.
Please reward if it helps.
Regards,
George

How to change the visible length in screen painter?

Hi Guys,
we have field in screen which is type to ATWRT but the visible length is set to 11. ATWRT is 30 char.
Please advise on How to change the visible length in screen painter to make it 30?
When I try to edit the defined length from 11 to 30. It wont allow me to.
Thanks a lot!

Hi,
Try the below method:
Goto Screen Painter -> Double click on Input-Output field for ATWRT another screen will appear with attributes of Input Output field -> Increase the Visible length Value there. (Option of visible length is below the Name and Text attribut of Attribute windiw.)
If the Visible length field isn't allowing change then declare it as a Char type instead of taking the DataType for Data Dictionary.
Thanks,
Preyansh

How to change the screen element of a single field in a table control

Hi Gurus,
I want to change the screen element of a single field (or the whole row) in a table control according to a condition.
I have 2 columns in the table control. One is an input column and one output only. When user enters values into the input column, they need to be compared against the values in the other column, and if there is a discrepancy, the row where the discrepancy is needs to be highlighted.
I have tried the following code which highlights the whole column ...
CONTROLS: TC_ZVOYG_BINS TYPE TABLEVIEW USING SCREEN 0500.
DATA: wa_tc_zvoyg_col LIKE LINE OF TC_ZVOYG_BINS-cols.
LOOP AT G_TC_ZVOYG_BINS_ITAB
           INTO G_TC_ZVOYG_BINS_WA.
    if G_TC_ZVOYG_BINS_WA-zdelivery_bin ne G_TC_ZVOYG_BINS_WA-zactual_bin.
      loop at screen.
        IF screen-name = 'ZVOYG_BINS-ZACTUAL_BIN'.
          wa_tc_zvoyg_col-screen-intensified = 1.
          MODIFY tc_zvoyg_bins-cols FROM wa_tc_zvoyg_col TRANSPORTING
          screen-intensified WHERE screen-name = screen-name.
        endif.
      endloop.
    endif.
endloop.
And also the following code which makes no change ...
LOOP AT G_TC_ZVOYG_BINS_ITAB
           INTO G_TC_ZVOYG_BINS_WA.
    if G_TC_ZVOYG_BINS_WA-zdelivery_bin ne G_TC_ZVOYG_BINS_WA-zactual_bin.
      loop at screen.
        IF screen-name = 'ZVOYG_BINS-ZACTUAL_BIN'.
          screen-intensified = '1'.
          modify screen.
        endif.
      endloop.
    endif.
endloop.
Thanks in advance.

Hi,
The modification of a screen element attribute (LOOP AT SCREEN...MODIFY SCREEN) must always be done in the PBO (for a dynpro, it will be in a PBO module, i.e. declared by MODULE ... OUTPUT)
About the loop at the internal table, it is done automatically by the system, also during the PBO, you'll find something like LOOP [AT itab] ... WITH CONTROL ... in the PBO part of the screen flow logic (note: you may have to complete with a supplementary READ TABLE if you don't use AT itab). So you don't need an additional loop.

Change Type of Screen Element in Report Program

Okay guys, I have been struggling with this the whole day.. someone please help me.
I have a selection screen defined in the selecton-screen of a report program
select-options : so_matnr for mara-matnr,
                 so_ebeln for ekpo-ebeln,
                 so_ebelp for ekpo-ebelp.
Now if I go to SE51 and give the program name and the screen number as 1000 (Default screen for report)
Now go to tab "Element List" --> "General Attributes"
in the column "Type of screen element" everything is considered as "I/O".
*Name*                 *Type of Screen Element*
%_SO_MATNR_%_APP_%-TEXT             I/O
%_SO_MATNR_%_APP_%-OPTI_PUSH     I/O
SO_MATNR-LOW     I/O
%_SO_MATNR_%_APP_%-TO_TEXT     I/O
SO_MATNR-HIGH     I/O
%_SO_MATNR_%_APP_%-VALU_PUSH     Push
%_SO_EBELN_%_APP_%-TEXT     I/O
%_SO_EBELN_%_APP_%-OPTI_PUSH     I/O
SO_EBELN-LOW     I/O
%_SO_EBELN_%_APP_%-TO_TEXT     I/O
SO_EBELN-HIGH     I/O
%_SO_EBELN_%_APP_%-VALU_PUSH     Push
%_SO_EBELP_%_APP_%-TEXT     I/O
%_SO_EBELP_%_APP_%-OPTI_PUSH     I/O
SO_EBELP-LOW     I/O
%_SO_EBELP_%_APP_%-TO_TEXT     I/O
SO_EBELP-HIGH     I/O
Now, my requirement is that I need to do something at the loop at screen to change the 'I/O' to 'Text' for all the %TEXT% screen fields. Exactly behave like text labels in the dialog program
Now, I don't want to write a dialog program to achieve this. Is there any thing i can do in the report program to achieve it.

Hello,
Try something like this:
INITIALIZATION.
loop at screen.
if screen-name eq <your field>
    screen-input = 0.
    modify screen.
endif.
endloop.
The important thing is to do it on INITIALIZATION event

Best Way To transfer screen elements to ABAP variables

Hi all,
whats the best way to attach the abap elements to screen elements
normally earlier versions before 4.7C i always used TABLES : MARC in abap program
and in screen design i used to click "GET from DICTIONARY" to design the screen in Screen painter
The advantage with this approach is all data base elements are attached to our screens like search helps
atomatic checks etc and more over all the information valid for a particular plant are retrived by the system search helps themselves like
for example on the screen we have screen elements/ fields Plant , MRP controller.
in the plant i typed "X110'.
now in the mrp controller i pressed F4 to search for valid mrp controller . Since we associated the screen elements with database elements with TABLES statement all the MRP controller relevent to that plant X110 are displayed. this is quite valid.
But i read usage of tables : in Object Oriented abap is Obsolete is this still the correct way of programming.
I can also use Some thing like this Data : st_marc type type MARC.
and in Screen design i can click "Get from program" This approach will loose all the database assignments to screen elements.
Now i can no longer retrieve the MRP controller relevent for plant 'X110'. F4 will show me all the MRP controllers in all plants.
Is there any other approach to do this. Thanks.

Hi there Fgonzalez2015,
You may find the camera troubleshooting steps in the article below helpful.
Get help with the camera on your iPhone, iPad, or iPod touch
You see a closed lens or black screen
If you see a closed lens or black screen when you open the Camera app, try these steps:
Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
Force the app to close, then open the Camera app again.
Restart your device, then open the Camera app again.
If your device has a front and rear camera, try both cameras by tapping the camera swap icon . If you see the closed lens or black screen on only one camera, take your device to an Apple Retail Store or Authorized Service Provider for more help.

In LabVIEW6i, is there a way to make particular elements of an array invisible while the others stay visible (without losing any element's info.)?

I have an array of clusters. Each cluster pertains to a certain oscilloscope I am controlling. There is another control which specifies which oscilloscopes I have "on".
If a particular oscilloscope is "on" I want its cluster to be VISIBLE in the array. If a particular oscilloscope is "off" I want its cluster to be INVISIBLE in the array.
How can I implement this in my program without losing ANY of the info. in my array?

I suggest to use two arrays; one for user interface holding the ON clusters,
and one for internal use holding all clusters. The diagram periodically
updates the internal array with user interface array data.
By INVISIBLE do you mean "skipped from the array" or displayed as an empty
placeholder? To hide an OFF cluster you could put in the cluster a flat
button boolean that is small and transparent when ON and large enough to
cover the whole cluster area (and other controls) when OFF.

You need to use the right arrow on the remote to go all the way to the right. The submit button will be highlighted and you can then press select on the remote to proceed.

Capturing the values of screen elements on click of execute button

Hello folks,
Is there a way to capture the values entered in the screen on click of the execute button?
What I want to do is, I have a selection screen where-in a user can fill the input fields (parameters and select-options). Now when the user clicks on the execute button, the values of all the screen elements (no matter if they are filled or empty) should be stored in variable, so that I can use these values again when I am calling this program from another program.
I want to do something similar to saving a variant, but this save should happen on click of Execute button and user need not require to explicitly save these values as variant.
Hope I am clear enough to put my query in front of you all.
It would be a great thing if you could help me.
Need your help.
Thanks in advance.

Hi,
You need something like this
REPORT A.
TABLES: sflight.
PARAMETERS: pa_scarr   TYPE sflight-carrid.
SELECT-OPTIONS so_conn FOR sflight-connid.
DATA: BEGIN OF it_selscr_values OCCURS 0.
        INCLUDE STRUCTURE rsparams.
DATA END OF it_selscr_values.
START-OF-SELECTION.
CALL FUNCTION 'RS_REFRESH_FROM_SELECTOPTIONS'
    EXPORTING
      curr_report     = sy-repid
    TABLES
      selection_table = it_selscr_values. "here you have all parameters' values from selection screen
"later in some other program you can use this table to call report A filling its selection screen with these default values like
SUBMIT a WITH SELECTION-TABLE it_selscr_values.

Why are the apps on my IPad scattered across the whole thing and when I open them they turn to little rectangles in the corner of the screen and I can't even use them or tap on anything. Also when I turn my iPad it doesn't flip the screen over

Hi The next thing to do is to Restore back to Factory Settings this will get rid of any bugs . After Restore use same Apple ID /Password then you should get all your Apps & data back If you still have this problem make an Appointment at Apple Store . Cheers Brian
